CANMOPENER.

SPECIFICATION forming part of Letters Patent No. 725,131, dated April 14, 1903. Application filed July 12,1902. Serial No. 115,383- (No model.)

To all when z, it may concern:

Be it known that I, FRANK PEFFER, a citizen of the United States, residing at Mount Joy, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Can-Opener, of which the following is a specification.

This invention relates generally to canopeners, and more particularly to one in which the circular opening is cut in the top of the can by means of a cutting-blade carried by an operating-handle; and the object of the invention is to provide a can-opener of this description which shall be exceedingly :5 cheap and simple in construction and quick and easy in adjustment, so that the cuttingblade can be quickly and easily adjusted for cutting the tops of different-sized cans.

The invention consists also in certain novel features of construction and combination,

all of which will be fully described hereinafter and pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a perspective view showing the practical application of my invention. Fig. 2 is a side elevation, partly in section. Fig. 3 is a transverse vertical section, and Fig. 4 is a transverse section show.- ing a slight modification.

In carrying out my invention I employ a shank A, which is preferably made a very peculiar shape in crosssection, the upper and side edges being rounded, as shown at A, while the bottom has a curved groove A produced therein. This shank A is provided with a suitable handle B at its rear end, While the forward end is provided with a point C, which is considerably less in diameter than the shank A and tapers to a point D, said point being bent at a right angle to the portion 0, as most clearly indicated in Fig. 2. This point D is projected through the center of the can and the Vertical portion 0 employed as a pivot upon which the shank is revolved by means of the handle B. The

shank A has a slide E, which has an opening produced therein to correspond with the shape of the shank A, a ridge F. fitting into the groove A produced in the shank. This construction insures a very easy movement of the slide upon the shank and avoids all danger of the slide turningupon the said shank. The slide E carries a cutting-blade F, which is preferably integral with the slide, although it may be separable therefrom. Further, one of the edges of the cutting-blade may be formed as a continuation of the slide E, as most clearly shown in Figs. 3 and 4. The shank has a series of recesses G produced in the top side thereof, which recesses are intended to receive a locking-pin carried by the slide for the purpose of holding the slide in its proper adjustable position on the shank, and this pin may be threaded, as shown at H in Fig. 3, or it may be smooth, as shown at H in Fig. 4. When the pin is threaded, it of course works in the threaded aperture produced in the slide and is provided with a milled head H When the pin is smooth, it works through a smooth opening and recesses produced in the slide, and within the said recesses and surrounding the pin is a coilspring I, the purpose of which is to hold the pin in its lowered position or in engagement with the recesses G. The slide can be moved in or out upon the shank, and by means of the construction shown in Fig. at it is only necessary to pull up on the pin, move the slide, and release the pin and it will immediately lock itself in engagement with the recess, inasmuch as the spring will project the said pin into-the recess. By having the shank of greater length between the upper and lower edges than between the side edges ample room is provided for the recess Gand for the guiding-groove A It will thus be seen that I provide a canopener capable of opening cans of various sizes and also one in which all of the parts can be quickly and easily adjusted.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A can-opener comprising a shank, having a series of recesses in the top side and the longitudinal groove in the bottom side thereof, a depending angular and pointed portion adapted for engagement with the recesses in arranged at the forward end of the shank, a the top of the shank, substantially as and for slide movable upon the shank, said slide havthe purpose specified.

ing a ridge adapted to engage the longitucli- FRANK PEFFER. nal groove in the shank and cutting-blade Witnesses: carried by the said slide, and the spring-ac- CLARENCE G. CRALEY,
